T rapped beneath a hostile alien
planet surface, you must control
your rotating auger to clear a
tunnel through which your three
spelunkers can escape. Barring
the malevolent Alien Bird Creature and its
brood of Probe Birds, even I could do it. But
these Probe Birds continually search the
tunnels, attempting to block you in with
mean green fungus, and if that doesn’t
paralyze you, their deadly nuclear rods are
released to complete their mission! Oh yes,
one more oh-no! You have only one alien
day/night to make your escape. And as you
read, the sun is beginning to rise . . .
To QUICKLY clear a tunnel through an
alien underground by which your intrepid
team of spelunkers can pass to safety.
TO BEGIN PLAY
Press fire button and “Quadrant 1” screen
will appear, press button again and “Use
Joystick” screen will appear, press again,
“Quadrant 1” screen will appear, then game
play begins. Or you can just wait a few
seconds and Title screen will automatically
move to “Quadrant 1” screen then to game
You will automatically start at Quadrant 1.
To preselect a higher level, press the
computer “select” button then move the
joystick to the right; to decrease, move the
joystick to the left, then press the fire button
to begin play.
Note: To pause the game, press “space”
bar; to resume play, press trigger on
There are 15 Quadrants (levels of play) as
you begin your challenge. If you make it
through the difficult 15th Quadrant,
84 more Quadrants are open to you— that’s
a total of 99!
At the start of each Quadrant, your rotating
auger is stationed at the left of the
underground. Just behind it is your first
spelunker awaiting his chance to escape to
safety. At the opposite side of the
underground is the escape tunnel through
which your spelunker must pass.
As play begins, the alien sun will rise and
set, moving left to right on the screen. As
soon as the sun sets, the moon rises and
sets. This sequence constitutes one alien
day and night. And very little time.
Control your rotating auger to
clear an unobstructed tunnel
from left to right so your
spelunkers can escape. Your
tunnel only has to be wide
enough to allow the spelunker to pass
through. Use the joystick to control the
direction of the movement. Push the fire
button to determine which of the two,
spelunker or auger, is in active
control. (The inactive element will dim
from white to gray.)
When boring through soft earth, the auger
moves at a normal pace. A boulder
or green fungus slows it considerably.
BE CAREFUL not to chew up your own
man with the auger.
Three spelunkers depend on
you to pass them through the
escape tunnel. Each is moved
one at a time with the joystick.
The second and third spe-
lunker cannot be brought into play unless
you have moved the preceding man from
the left of the screen to the right and out the
exit, or the preceding man was destroyed.
You have one alien day/night in which to
move each spelunker from left to right.
More time means a dead spelunker. When
one man reaches the exit, or is eliminated
along the way, the next moves into play and
another day/night cycle begins.
After all your spelunkers have escaped,
you’ll automatically move up to the next
level of play. At the successful completion
of every five successive Quadrants, you will
gain one bonus spelunker. Hot Shots stand
to gain five.
ALIEN BIRD CREATURE
Enter the Alien Bird Creature,
atmosphere left. Immediately,
it releases three Probe Birds.
In Quadrants 2 through 99,
the Creature will also periodically bombard
the underground with pairs of deadly
magna-titanium rods and block your path.
Since these rods are dropped at random,
they may strike and destroy a Probe Bird.
But before you breathe a sigh of relief,
the Bird Creature may release a replace-
ment Probe Bird.
ALIEN PROBE BIRDS
Three drones move about the
inserting their fungus injectors
into the subsurface area in
hopes of locating and destroying you. *ln
the multi-player format, additional players
join in for only one purpose— to control
Probe Birds. Since there are 3 Probe Birds,
3 additional players can join in the game.
Scattered about the
underground are granite
boulders. The higher the level
of play, the greater number of
boulders you have to contend with. As you
might expect, drilling through them with
your auger slows you down quite a bit.
Blast boulders in your path—
BOOM! Create new tunnels—
BOOM! Kill a Probe Bird—
BOOM! The number of bombs
your spelunker gets is the number you see
in the center bottom of the screen. You
won’t actually see the bombs you possess
until your spelunker detonates them, but
you can count on five at the start of any
Quadrant. And receive an additional bomb
upon the successful completion of each
Quadrant. Now that your spelunker has
bombs, to detonate one, quickly turn your
joystick in a complete circle (clockwise)
Plus— a blue bonus bomb
wanders about each
Quadrant. It’s only visible in
an area which has been
cleared. If your spelunker can touch it, he
owns it, and can detonate it. Ten seconds
after he gains possesion of it, a new bomb
appears. You can accumulate as many as
99 bombs in your arsenal.
Watch out for the Probe Birds’ nuclear
rods. They’re dropped randomly and if they
strike you, you’re dead. Also, these rods
penetrate underground areas where
openings occur and release deadly fungal
tablets which kill on contact. Otherwise,
these tablets spray the tunnel with creeping
green fungus. Once the fungus is formed,
your escape route is blocked and must be
drilled through by your auger or side-
stepped by your spelunker. If the rod
strikes a granite boulder or mass of
previously injected fungus, the rod’s
penetration is s-l-o-w-e-d d-o-w-n. If a rod
strikes a fog nodule at the surface level, it
retracts. Watch closely. Panic accordingly.
To kill a Probe Bird: Wait until it drops a
nuclear rod, then deposit a bomb close
enough to the rod to make sure the
explosion will touch the injector. The
detonation must occur before the injector is
released by a Probe Bird. If successful, the
injector will retract upward and blow up the
Probe Bird— BOOM!
Alien Bird Creature
GAME S OVER!
The game ends when all of
your spelunkers are destroyed.
At that point, a Top Ten Score
display appears upon which a
player may enter up to seven
characters if his score is among
the Top Ten.
Bombs at Your Disposal
Point scoring is based upon how long it
takes you to move a spelunker to the
When play begins, the Potential Score
display in the right hand corner shows your
potential score per man at the start of the
day/night time frame. This point total will
continually decrease by 10 points as the
day/night passes. The potential point
display will recycle to its start number when
a spelunker is eliminated, or you have
gotten a man through to safety, or you
advance to the next Quadrant.
When you successfully move a man
through the escape tunnel, the potential
number of points then shown are
transferred to your Player Score display in
the left corner of the screen.
Quadrants are distinguished by an
increasing number of potential points to be
scored. Quadrant 1 allows a maximum of
1,000 points per man, Quadrant 2, 2,000
points and so forth, up to Quadrant 10 with
10,000 points which is the maximum you
2-3-4 PIAYLR VERSION
Up to 3 more players can join in, to control
the Probe Birds! First, plug your joysticks
into ports #2, #3 and #4 for the multi-player
format. Next, press the button on your
individual joystick, and see one Probe Bird
freeze and change color. That’s the one you
control. Move joystick left and right, up or
down. (As soon as you stop moving the
joystick, the computer takes over.)
Now, use your joystick to maneuver your
Probe Bird as close to the surface as
possible, then pull joystick towards you and
a nuclear rod will begin its descent. When
its tip reaches a tunnel, release joystick and
rod will drop from bird and begin spreading
its green fungus in the tunnel. If you decide
against dropping the rod, push joystick
away from you and rod will retract.
Game status is shown in the “window” at
the bottom of the screen. Displays include
a running Player Score total on the left, a
Potential Score on the right; and Quadrant
number in the upper center. The spelunkers
yet to be moved to safety are shown just
above the Player Score. Those already safe
are shown just above the Potential Score.
1 . Keep your auger close to your spelunker
since you’ll need to clear your tunnel of
granite and fungus often.
2. An overhead tunnel can catch the
fungus, making it easier for you to
escape through a second tunnel.
